Background: Ultrasound investigation potentials in lymphedema are still to be fully used in everyday practice. Aim of the present study was to report the sonographic characterization of the dermo-epidermal complex (DEC) and of the subcutaneous (SUBC) tissue, assessing the feasibility of a related mapping, in upper limb secondary lymphedema. Methods: In this retrospective study 287 patients affected by monolateral upper limb post-mastectomy lymphedema (M5/F282; mean age 64±4.24) were enrolled and scanned by ultrasound, considering the healthy contralateral limb as control. In order to standardize the assessment, the limb was divided in sectors: 4 anterior, 4 posterior below the elbow, 4 anterior and 4 posterior above the elbow, plus the hand. DEC and SUBC regions B-mode appearance were reported, both in the healthy and in the pathological arms. DEC thickness was measured and compared among the same sectors of the healthy and pathological limbs. Results: DEC and SUBC sonographic appearance was differentiated in fluid and sclerotic. DEC included a third category characterized by differentiation loss. The different sectors showed significantly different lymphatic involvement in the affected limb. In the comparison with the contralateral unaffected segments a significantly thicker DEC was reported in the forearm affected by lymphedema (P<0.005), while no significant difference was reported at the arm level. Conclusions: Traditional ultrasonography can provide a secondary upper limb lymphedema characterization with related mapping and useful data for a better lymphatic physiopathology understanding and for a properly addressed therapeutic protocol.

Abstract
Background: Ultrasound investigation potentials in lymphedema are still to be fully used in everyday practice. Aim of the present study was to report the sonographic characterization of the dermo-epidermal complex (DEC) and of the subcutaneous (SUBC) tissue, assessing the feasibility of a related mapping, in upper limb secondary lymphedema. Methods: In this retrospective study 287 patients affected by monolateral upper limb post-mastectomy lymphedema (M5/F282; mean age 64±4.24) were enrolled and scanned by ultrasound, considering the healthy contralateral limb as control. In order to standardize the assessment, the limb was divided in sectors: 4 anterior, 4 posterior below the elbow, 4 anterior and 4 posterior above the elbow, plus the hand. DEC and SUBC regions B-mode appearance were reported, both in the healthy and in the pathological arms. DEC thickness was measured and compared among the same sectors of the healthy and pathological limbs. Results: DEC and SUBC sonographic appearance was differentiated in fluid and sclerotic. DEC included a third category characterized by differentiation loss. The different sectors showed significantly different lymphatic involvement in the affected limb. In the comparison with the contralateral unaffected segments a significantly thicker DEC was reported in the forearm affected by lymphedema (P<0.005), while no significant difference was reported at the arm level. Conclusions: Traditional ultrasonography can provide a secondary upper limb lymphedema characterization with related mapping and useful data for a better lymphatic physiopathology understanding and for a properly addressed therapeutic protocol.File | Dimensione | Formato | |
